例句：

1. Catalase is a crucial enzyme that protects the cells from the damage caused by hydrogen peroxide.（酶是一种关键酶，它可以保护细胞免受造成的伤害。）

2. The catalase activity in liver cells decreases with age.（肝细胞中的酶活性随着年龄增长而减少。）

3. Exposure to high levels of hydrogen peroxide can lead to a decrease in catalase activity.（暴露在高浓度的中会导致酶活性下降。）

4. Catalase plays an important role in the metabolism of alcohol in the liver.（酶在肝脏中乙醇代谢中起着重要作用。）

5. Some plants have high levels of catalase, which help them to survive in harsh environmental conditions.（一些植物含有较高水平的酶，有助于它们在恶劣的环境条件下生存。）

6. Catalase deficiency can lead to a condition called acatalasia, which causes an accumulation of hydrogen peroxide in the body.（酶缺乏可以导致一种称为无酶症的疾病，这会导致体内的积累。）

7. The catalase activity in blood can be used as a biomarker for oxidative stress.（血液中的酶活性可以作为氧化应激的生物标志物。）
